GRAlN-SEPARATOR.

SPECIFICATION forming part of 'Letters Patent No. 272,178, datedFebruary 13, 1883. Application filed September 12,1882. (No model.)

T all whom it may concern Be it known that I, MARTIN WILCOX, ofPaskenta, county of Tehama, State of California, have invented anImproved Grain-Separator; and I hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to improved means for separating wheat frombarley,oats, and small grains or seeds after the grain has been cleanedfrom the straw and chafi".

Figure l isa perspective view of my improved wheat-cleaning apparatuswith a portion of one side broken away. Fig. 2 is a longitudinalvertical section of the same. Fig. 3 is a transverse section of thesame.

A is a suitable framework, in which the mechanism is supported.

B is a hopper, from which the grain is discharged through aregulating-gate upon an inclinedmoving belt or draper, G, which lies atan inclination of about thirty degrees, more or less, as the workrequires, and moves upward. Above this belt is a blower,D, orothersuitable blast apparatus, so arranged as to discharge a blast of air upthe face of the belt and against the (lescending grain. A windgate, E,self-adjusting by its own gravity, made of canvas or other flexiblematerial, is supported above the belt, and may be used to regulate theblast upon the belt. At the foot of the beltO, with a little spacebetween, is placed a pivoted inclined division-board, M, to receive aportion of the descending grain from the belt G and discharge it beyondthe belt H. When the air-blast is on and belt 0 is in motion graindropped on the upper end of the belt U will roll downward; Thefullformed heavy kernels of wheat move downward faster than the beltmoves upward and drop at the lower end of the belt, whereas 'shriveledwheat, oats, cheat, and barley, moving slower, are carried up and off atthe upper end. Of what passes down the belt, the larger, heavier kernelsacquire a velocity that carries them onto and'beyond the-inclined boardM, whereas the lighter, slower'part falls short upon the belt H. Of whatis discharged from the upper end'of the belt, the lightest portion isdriven by the air-blast off above the smut-board F. The heaviestfallsnpon board G, and that of medium weight passes down between boardsF and G.

G is a board to receive any good grain which may be carriedbver theupper end of the belt (I, but not with sufficient force to pass beyondthe end of this board, as the smutty grain does. This board stands at anincline in the same direction as the belt 0, and is also tilted, so thatgrain moving down it will also move to one side and be discharged fromthe lower edge, so as to fall upon the higher edge of the belt H. Thisbelt, which also receives grain from the lower end of the belt 0, hasits receiving end slightly inclined from a horizontal plane, (taken inatransversedirection,)and this inclination gradual y increases towardthe opposite end, so that at that end the inclination is quite steep.This arrangement of belt H enables me to separate the wheat from oatsand other impurities by gravitation. The good wheat, with full kernels,will roll off the most moderate incline. The lighter, shriveled wheatwill remain and be carried along by the belt until the incline becomesgreat enough to discharge it, while the cats will either lie upon theirflattened sides or will roll until the larger ends of the grain,outrunning the smaller, will lielengthwise downtheincline and stop. Thisbelt passes around a roller at each end, and is driven by belt-pulleysfrom any convenient moving pulley upon the machine. ward movement thedifferentqualitiesof grain are carried along so as to be discharged atdifferent points over the edge of the belt, falling upon a shakingscreen, I, which stands at a slight angle transversely. This screenissuspended by spring-arms J J, and is given a shaking motion by theaction of the angular portion of the shaft K, which strikes a projectingend, j, of the spring-rod J, and gives it, together with the screen I,ashaking motion. This separates the smaller seeds, which will fallthrough the screen, while the different grades of wheat will bedischarged over its edge opposite the points where they are dischargedupon it from the inclined belt H. By this construction, and thearrangement of the moving belt H, inclined sidewise, I am enabled chargeit upon-the screen at difierent points,

By its for- -to distribute the grain along this belt and disso as toseparate seed -wheat, milling and market wheat from impurities and fromeach other at one running.

Having thus described my inventiomwhat I claim as new, and desire tosecure by Letters Patent, is-- 1 In a grain-separator, a grain-carryingbelt, H, having from one end toward the other a progressively-increasedsidewisc inclination, substantially as described.

2. In a grain-separator, the belt H, inclined in a plane transverse toits line of travel, in combination with the screen I, suspended beneaththe lower edge of belt H, and mechanism togive said screen a shakingmotion,

substantially as specified.

3. In a grain-separator, the traveling belt H, inclined in a planetransverse to its line of travel,the screen I, the hopper B,and inclinedbelt 0, in combination with the blower D, self- 20 adjusting gravitywind-gage E, and the inclined direction-board F, substantially as hereindescribed.

In witness whereof I hereunto set my hand.

MARTIN VVILCOX.
